[IDENTIFICATION OF LEPTOSPIRA SEROVARS BY MALDI-TOF MASS-SPEC- TROMETRY].

Aim: An attempt to use MALDI-TOF mass-spectrometry method for identification of lep- tospiral isolates on the serovar level.

Materials And Methods: 8 reference Leptospira spp. and 11 leptospira strains isolated from leptospiral patients and infected animals in the North-Western region of Russia were included into the study.

[MALDI-TOF MASS-SPECTROMETRIC ANAIYSIS OF LEPTOSPIRA SPP. USED IN SERODIAGNOSTICS OF LEPTOSPIROSIS].

Aim: Creation of a classification model of Leptospira spp. serovar model using ClinProTools 3.0 software and evaluation of use of MALDI-TOF MS as a method of quality control of reference strains of leptospira.

[Determination of melatonin receptors in human blood mononuclear cells: clinical and experimental rationale].

Melatonin is a mammalian hormone that has a great variety of effects. At present there is evidence that this hormone considerably reduces the manifestations of many gastrointestinal inflammatory diseases. The biological effects of melatonin are realized through the receptors located on the membranes of different animal cells.
